JOHN R. BOILEAU, OF MINOCQUA, WISCONSIN.

WINDOW.

Application filed May 15,1913.

To all whom it may, concern Be it known that I, JOHN R. BOILEAU, acitizen of the United States, and a resident of Minocqua, in the countyof ()neida and State of \Visconsin, have made certain new and usefulImprovements in \Vindows, of which the following is a specification.

My invention is an improvement in windows, and hzs for its object toprovide a means capable of being applied to an ordinary window, forconverting the said window into an extension or bow-window, forpermitting the occupants of the room to see laterally as well asdirectly upward, and which may be inclosed by a perforate covering inwarm weather, for preventing the entrance of insects, dust and the like,or with an impel-forate transparent covering in winter, to prevent theentrance of cold air, while at the same time permitting an unobstructedview.

In the drawings: Figure 1 is a perspective view from the outside of theimproved window, Fig. 2, is a section on the line 2 of Fig. 3, lookingin the direction of the arrows, Fig. 3 is a section on the line 3-3 ofFig. 2, looking in the direction of the arrows, Fig. 4 is a view of aportion of Fig. 2, showing a perforate covering, Fig. 5 is a perspectiveview from in front and above, of a modified construction, and Figs. 6and 7 are sections on the line 6-6 of Fig. 5 and 7-7 of Fig. 6,respectively, both looking in the direction of the arrows.

In the embodiment of the invention shown in Figs. 1 to 3, the improvedwindow comprises a box-like structure, consisting of a bottom 1, a top2, sides 3, and a front 1, the said bottom, top, sides and front beingof integral construction, and properly shaped, the bottom being planeand horizontal, while the top 2 inclines downwardly toward its outer endand toward the front 4. Both the bottom and the top are provided withintegral laterally extending flanges 5 and 6 respectively, and the sides3 are provided with similar flanges 7. As shown, the sides 3 and thefront 4 are provided with openings 8 and 9 respectively, the saidopenings extending over the greater portion of the area of the saidsides and front. The sides 3 are provided with guideways 10 on theirouter faces encircling the openings 8, for receiving sheets 11 oftransparent imperforate material, as for instance glass, or forreceiving sheets 12 of perforate material, as for in- Specification ofLetters Patent.

stance wire screen, as shown in Fig. 1. The front a of the window isalso provided with guidewalvs l3 encircling the opening 3), for receiiing sheets 14 of imperforate ranspar ent material, or for receivingsheets 15 of perforate material, as may bedesired. The guideways 10 or13 may be omitted at one side of each opening, as shown at the top ofthe front t in Fig. .2, to permit the insertion and removal of thesheets 11 or Each of the flanges 7 of the sides 3 is provided withalined vertical spaced bearings 16, and a handle 17 is connected witheach pair of.

bearings, each of the said handles being in the form of a bail havinglateral lugs 18 for engaging the bearings. The said lugs 18 are offsetlaterally from the handle portion or body of the bail, and the saidbails may be turned into the position of Figs. 2 and 3 or flat on theflanges. The imperforate top 2 is as before stated inclined toward thefront 4 so that rain, and the like, will not stand on the top, but willflow toward the front. The sides 3 are also inclined, convergingslightly toward tie front 4, as shown more particularly in Fig. 3. Theimproved window is placed in the position shown in Figs. 2 and 3. thebottom 1 resting on the sill 19 of the window, and the bottom rail 20 ofthe lower sash resting upon the top The flanges 5, (3 and 7 are engaged.with the inner faces of the casing of the window, the flange 5 fittingagainst the inner face of the sill, while the flange (3 extends acrossbetween the said members of the casing. The flanges 7 are engaged withthe inner face of the said members, as shown in Fig. 3.

When it is desired to remove the extension or bow-window, the bails 17are grasped, and the extension window is moved inwardly. In summer theperforate coverings l 12 and 13 are arranged in the openings of thesides and front, while in winter the transparent imperforate sheets 11are made use of. The improved window may be utilized as a conservatoryfor plants, to eX- pose the same to the sun, and with the perforatecoverings in place, the plants are also exposed to the air. Forconservatory use, the top 2 may also be provided with an opening coveredwith imperforate transparent material, or perforate material as may bedesired. The bottom 1 may also be formed with an opening similarlycovered.

The device is especially adapted for upstairs dwellers, as for instancein apartment houses and the like, and may be used as a t The said frame32 is ventilating device, or as a storm window. In the construction ofFigs. 1 to 3, and Fig. 4, the extension windows are made in sizes to fitthe windows in which they are to be used, the said extension Windowsbeing of a width at their open sides corresponding to the width of theeasement, and of a height provided with bear- 1 l corresponding to theheight of the lower! ings at each of its side edges, the said bearingsfitting between the bearings 31 of the sides, and rods 34 are passedthrough the alined bearings for hinging the frame to the sides. The saidframe 32 is provided with guideways extending on each side and along thebottom of the opening of the frame, and on the outer face thereof, forreceiving a sheet 36 of transparent imperforate material. At each endthe frame 32 is provided with an inwardly extending approximatelysemi-circular flange or ex tension 37 and 38 respectively. The flange 37extends below the overlapping extensions 28, and the flange 38 extendsbelow the overlapping extensions 29, and both of the flanges 37 and 38lap upon the adjacent extensions to cover and make a tight top andbottom for the extension window. The de vice just described is used inprecisely the same manner as the construction of Figs. 1 to 3, and thesaid device is capable of adjustment to fit windows of various sizes.

I claim z- An. extension or bow-Window comprising side frames and afront frame, a hinge connection between each side edge of the frontframe and the adjacent side edge of the adjacent side frame, the sideframes having inwardly extending lateral extensions at their upper andlower ends, said extensions being adapted to lap upon each other, thefront frame having at each end a lateral inwardly extending flangeadapted to underlie the extensions of the sides.

sash. The extension window is easily handled by means of the bails.

In the construction of Figs. 5, 6 and 7, the improved window is composedof a sectional top and a sectional bottom. In the said constructionsides 21 and 22 are provided, each having a lateral flange 23, and eachof the said sides is provided with an opening 21. in sheet 25 ofperforate material is arranged on the outer face of each of the saidsides at the opening, way 26 is arranged on the inner of the said sides,each of the circling three sides of the shown, the inner side of theopening is free, so that a sheet 27 of imperforate transparent material,as for instance glass, may be inserted in the guideways. Each side isthus provided with a perforate and an imperforate transparent covering.Each of the sides 21 and 22 is also provided at each of its ends with alateral extension 28 and Q9. The said extensions are of an ag regatewidth equal to the Width of the casement in which the extension windowis to he used, and at their outer ends the said flanges overlap, asindicated at 30 in Figs. 5 and 7. At its outer edge, each of the sides21 and 22 is provided with a plurality and a guideface of each guidewaysenopening. As

of bearings 31, and an open frame 32 is ar- \Vitnesses: ranged betweenthe outer ends of the said U. T. Auras,

sides and between the extensions 28 and 29. TIIICO. BOSACKI.
